If v, = (2,4) and v2 = (-1,5), then w,-V is equal to which of the following?O 18O (-2. 20)O 22O (8.-5)

Answers

Answer 1

We are given the following matrix:

[tex]A=\begin{bmatrix}{4} & {-7} & {} \\ {-2} & {1} & {} \\ {} & {} & {}\end{bmatrix}[/tex]

We are asked to determine the coefficients of:

[tex]A^{-1}[/tex]

Which is the inverse matrix. To do that let's remember that the inverse of a 2 by 2 matrix of the form:

[tex]A=\begin{bmatrix}{a_1} & {a_2} & {} \\ {a_3} & {a_4} & {} \\ {} & {} & {}\end{bmatrix}[/tex]

is:

[tex]A^{-1}=\frac{1}{\det A}\begin{bmatrix}{a_4} & {-a_2} & {} \\ {-a_3} & {a_1} & {} \\ {} & {} & {}\end{bmatrix}[/tex]

The value of the determinant of A (det A) is given by:

[tex]\det A=a_1a_4-a_2a_3[/tex]

Replacing we get:

[tex]A^{-1}=\frac{1}{a_1a_4-a_2a_3}\begin{bmatrix}{a_4} & {-a_2} & {} \\ {-a_3} & {a_1} & {} \\ {} & {} & {}\end{bmatrix}[/tex]

Replacing the values:

[tex]A^{-1}=\frac{1}{(4)(1)-(-7)(-2)}\begin{bmatrix}{1_{}} & {7_{}} & {} \\ {2_{}} & {4_{}} & {} \\ {} & {} & {}\end{bmatrix}[/tex]

Solving the operations:

[tex]A^{-1}=-\frac{1}{10}\begin{bmatrix}{1_{}} & {7_{}} & {} \\ {2_{}} & {4_{}} & {} \\ {} & {} & {}\end{bmatrix}[/tex]

Or:

[tex]A^{-1}=\begin{bmatrix}{-\frac{1}{10}_{}} & {-\frac{7}{10}_{}} & {} \\ -{\frac{1}{5}_{}} & {-\frac{2}{5}_{}} & {} \\ {} & {} & {}\end{bmatrix}[/tex]

Therefore, we have:

[tex]\begin{gathered} a=-\frac{1}{10} \\ b=-\frac{7}{10} \\ c=-\frac{1}{5} \\ d=-\frac{2}{5} \end{gathered}[/tex]

The tour bus can seat 55 passengers.

A minimum of 15 people must register for the tour to book the bus.

This means that the number of people that must register for the tour must be greater than or equal to 15 and less than or equal to 55.

Let the number of people that must register be x.

Answers

Hello there. To solve this question, we need to calculate the percentage of households that owns a 4K TV with the values given in the sample and compare with the other percentage to see if the value has increased.

Using that sample of 300 households, in which 60 of them owns a 4K TV, we get that the percentage will be calculated by the ratio:

60/300

Simplify the fraction by a factor of 60

1/5

Multiply it by 100%

20%, equal to 0.20

In 2014, we had that percentage being equal to 18%, which is equal to 0.18

So, we do have sufficient evidence that the percentage of households satifying this situation have increased with the time.

How many baseballs with a diameter of 2.90inches, can fit into a box that is 48in x 40in x36in?

Answers

Answer:

5413 baseballs

Explanation:

Dimensions of the box = 48in x 40in x 36in.

The diameter of one baseball = 2.90 inches

Radius = Diameter ÷ 2 = 2.90 ÷ 2 =1.45 Inches

First, we find the volume of one of the baseball.

The baseball is in the shape of a sphere and:

[tex]\text{Volume of a Sphere}=\frac{4}{3}\pi r^3[/tex]

Therefore, the volume of one baseball will be:

[tex]\begin{gathered} =\frac{4}{3}\times\pi\times1.45^3 \\ =12.77in^3 \end{gathered}[/tex]

Next, we find the volume of the box.

[tex]\begin{gathered} \text{Volume of the box}=48\times40\times36 \\ =69120in\text{.}^3 \end{gathered}[/tex]

Therefore, the number of baseballs that will fit into the box will be:

I don't understand how to do this problem. Could you explain to me how to do this problem? The formula for the perimeter of a rectangle is P=2l + 2w, where l is the length and w is the width. A rectangle has a perimeter of 24 inches. Find it's dimensions if it's length is 3 inches greater than it's width.

Answers

Given:

• Perimeter of the rectangle = 24 inches

,

• The length is 3 inches greater than it's width.

Let's find the dimensions of the rectangle.

To find the dimensions, apply the formula for perimeter of a rectangle:

P = 2l + 2w

Where l is the length and w is the width.

Given that the length is 3 inches greater than the width, the length can be expressed as:

l = (w + 3) inches

Substitute 24 for P and (w + 3) for l in the formula:

P = 2l + 2w

24 = 2(w + 3) + 2w

Let's solve the equation for w:

24 = 2(w + 3) + 2w

APply distributive property:

24 = 2(w) + 2(3) + 2w

24 = 2w + 6 + 2w

Combine like terms:

24 = 2w + 2w + 6

24 = 4w + 6

Subtract 6 from both sides:

24 -6 = 4w + 6 - 6

18 = 4w

Divide both sides by 4:

[tex]\begin{gathered} \frac{18}{4}=\frac{4w}{4} \\ \\ 4.5=w \\ \\ w=4.5\text{ } \end{gathered}[/tex]

The width of the rectangle is 4.5 inches.

Since the lengh is 3 inches greater than the width, add 3 to 4.5 inches to get the length of the rectangle.

l = w + 3

l = 4.5 + 3

l = 7.5

The length of the rectangle is 7.5 inches.

Therefore, the dimensions of the rectangle are:

Length = 7.5 inches

Width = 4.5 inches

ANSWER:

Length = 7.5 inches

Width = 4.5 inches

Answers

Each burrito costs $3 and each taco costs $1.50.

How to calculate the equation?

Let b = variable for burrito

Let t = variable for tacos.

The equation based on the information will be illustrated as:

t + 3b = 10.50 .... i

2b + 2t = 9 ..... ii

From equation i, t = 10.50 - 3b. Put this into equation ii

2b + 2t = 9 .

2b + 2(10.50 - 3b) = 9

2b + 21 - 6b = 9

Collect like terms

4b = 12

b = 12/4

b = 3

Burrito = $3

Since t + 3b = 10.50

t + 3(3) = 10.50

t + 9 = 10.50

t = 10.50 - 9

t = 1.50

Taco= $1.50

Answers

Looking at the restrictions over the variable x, we know that the domain is:

[tex]x\ge2[/tex]

To find the range, notice that:

[tex]\sqrt[]{x-2}\ge0[/tex]

On the other hand, the function:

[tex]y=\sqrt[]{x-2}[/tex]

is an increasing function (its value grows when x grows), and can get as large as we want provided a sufficiently large value for x. Then, the range of such a function would be:

[tex]y\ge0[/tex]

Which does not get altered when we multiply the square root of (x-2) by 4.

Since the function:

[tex]y=-5+4\sqrt[]{x-2}[/tex]

is a 5-units shift downwards, then the variable y can take any value from -5 onwards.

Then, the range of the function is:

[tex]y\ge-5[/tex]

Another way to find the range is to isolate x from the equation:

[tex]\begin{gathered} y=-5+4\sqrt[]{x-2} \\ \Rightarrow y+5=4\sqrt[]{x-2} \\ \Rightarrow\frac{y+5}{4}=\sqrt[]{x-2} \\ \Rightarrow(\frac{y+5}{4})^2=x-2 \\ \Rightarrow x-2=(\frac{y+5}{4})^2 \\ \Rightarrow x=(\frac{y+5}{4})^2+2 \end{gathered}[/tex]

Since we already know that x must be greater than 2, then:

[tex]\begin{gathered} 2\le x \\ \Rightarrow2\le(\frac{y+5}{4})^2+2 \\ \Rightarrow0\le(\frac{y+5}{4})^2 \\ \Rightarrow0\le|\frac{y+5}{4}| \\ \Rightarrow0\le|y+5| \end{gathered}[/tex]

From here, there are two options:

[tex]\begin{gathered} 0\le y+5 \\ \Rightarrow-5\le y \\ \text{ Or} \\ 0\le-y-5 \\ \Rightarrow y\le-5 \end{gathered}[/tex]

Since we know an equation for y, then:

[tex]\begin{gathered} -5\le-5+4\sqrt[]{x-2} \\ \Rightarrow0\le4\sqrt[]{x-2} \end{gathered}[/tex]

Or:

[tex]\begin{gathered} -5+4\sqrt[]{x-2}\le-5 \\ \Rightarrow4\sqrt[]{x-2}\le0 \end{gathered}[/tex]

The second case is not true for every x.

Therefore:

[tex]-5\le y[/tex]

Therefore:

[tex]\begin{gathered} \text{Domain: }x\ge2 \\ \text{Range: }y\ge-5 \end{gathered}[/tex]

We know by the pythagorean theorem that

We know that the length of the hypotenuse squared will be equal to the sum of the legs squared. The problem says that the legs have the exact same length and the hypotenuse is 6cm longer, so we can write

Where "a" is the leg length, see that we can apply the pythagorean theorem here, and it will be

[tex]a^2+a^2=(a+6)^2[/tex]

See that now c = a + 6, and b = a.

We can simplify that expression

[tex]\frac{-b\pm\sqrt[]{b^2-4ac}}{2a}[/tex]

Using it

[tex]\frac{-12\pm\sqrt[]{12^2-4\cdot(-1)\cdot36}}{2\cdot(-1)_{}}[/tex]

Now we can just do all the calculus

[tex]\frac{-12\pm\sqrt[]{144^{}+144}}{-2_{}}=\frac{12\pm\sqrt[]{2\cdot12^2}}{2}=\frac{12\pm12\sqrt[]{2}}{2}[/tex]

Then the solution are

[tex]\begin{cases}a_1=6+6\sqrt[]{2} \\ a_2=6-6\sqrt[]{6}\end{cases}[/tex]

Even though we have two solution, see that the second one is negative, and we can't have negative length! Then the length of its legs will be

[tex]a=6+6\sqrt[]{6}[/tex]

And the hypotenuse will be a + 6, then

[tex]h=6+6+6\sqrt[]{6}=12+\sqrt[]{6}[/tex]

Therefore, the legs and the hypotenuse length is

[tex]\begin{gathered} l=6+\sqrt[]{6} \\ h=12+6\sqrt[]{6} \end{gathered}[/tex]

We can write it approximately as

[tex]\begin{gathered} l=14.485\text{ cm} \\ h=20.485\text{ cm} \end{gathered}[/tex]

If we want a more rough approximation we can say it's

[tex]\begin{gathered} l=14.5\text{ cm} \\ h=20.5\text{ cm} \end{gathered}[/tex]
